Devices And Methods For The Visualization And Localization Of Sound

摘要

Methods and devices are provided for processing sound signals, localizing sound signals corresponding to one or more sound sources, and rendering, on a wearable display device, an acoustic visualization corresponding to localized sound sources. A wearable visualization device may include two or more microphones for detecting sounds from one or more sound sources, and display devices for displaying the acoustic visualizations, optionally in a stereographic manner. A sound source may be located by processing the sound signals recorded by the microphones to localize sound signals corresponding to a given sound source, and processing the localized sound signals to identify the location of the sound source. The acoustic visualization may be a frequency-domain visualization, and may involve a mapping of frequency to color. The acoustic visualization devices and methods provided herein may assist in training the human brain to comprehend sound visualization signals as sound signal itself.

主权项

1. A method of rendering an acoustic visualization on an acoustic visualization device, the acoustic visualization device comprising a wearable display device and two or more microphones, the method comprising:
recording, via the microphones, sound signals from one or more sound sources; processing the sound signals to extract localized sound signals associated with at least one of the sound sources; rendering, on the acoustic visualization device, an acoustic graphic providing a visual representation of the localized sound signals; receiving input from a user identifying a selected sound source from a plurality of identified sound sources; generating a filtered audio signal comprising sound signals from the selected sound source, whereby sound sources other than the selected sound source are filtered; and providing an audio output comprising the filtered audio signal.
